Add "prev"/"next" buttons to Environments component

[mcicolella]

See here (old Polymer client)

You can move from an environment to another one.

Basically, the scope of this issue is to add a carousel like behavior. You could start from EnvironmentsPanel.vue component and add a carousel there.

This vue-carousel seems a good candidate.

It seems good. I have just made a test but it shows no environment.
Maybe I'm missing something.

c799232 introduced a carousel like behavior based on the old Polymer client.
The two buttons are not showed at first loading and after a page refresh.
They appear after logging out and logging in again.
